I don't know the actual physical terms, but alignment aims to center the mass of the knee over the center of the foot and that puts the center of weight over the middle of the ski (a balanced position).
A person that is real bowlegged has the center of their knee well outside of their foot, so their weight is much farther from the inside edge of their ski. For comparison, on a ski with a 70mm waist a balanced skier has their weight 35mm from the edge, but the bowlegged skier may have their weight 50mm from the edge (and the extra effort to get that leverage is equivalent to the balanced skier skiing on a 100mm ski).
I hadn't heard the idea of canting the boots to compensate for wide skis, sounds like you might just as well mount the bindings off center to get more weight over the inside edge.
